DRINKm'G-GUP.

Specification of Letters Patent.

Patented Oct. s, 1918.

Application filed May 8, 1916. Serial No. 96,216.

To all whom it may concern:

Be it known that 1, JAMES F. MCGHEE, a citizen of the United States, andresident of (ity Point, in the county of Prince George and State ofVirginia, have invented a new and useful Drinking-Cup, of

which the following is a specification.

M invention relates to drinking cups and i more particularly to thatclass of drinking cups which are constructed from paper and are known asindividual, sanitary drinking cups. These paper drinking cups areordinarily arranged in the receptacle or holder in compact form and itis necessary to insert the fingers in the cups to open them for drinkingpurposes, thereby rendering the same wholly unsanitary.

With this in mind, the primary object of the present invention is toprovide an individual drinking cup which may be opened without insertingthe fingers therein, thereby eliminating the danger of any germs or dirtbeing deposited upon the interior of the same.

Another important object of this invention is to construct a cup of theabove mentioned character having reinforcings that paper cupsmanufactured heretofore do not possess.

A further object of my invention is to provide a sanitary paper drinkingcup which is formed from a single blank thereby rendering it simple andinexpensive to manufacture.

The above and other objects and advantages of my invention will fullyappear -from the following description taken in connection with theaccompanying drawings and be explicitly defined in the appended claims.I wish it to be understood that this disclosure is illustrative only andthat the principle of my invention can be embodied in constructionsother than the ones specified.

In the embodiments of the invention herein disclosed, like referencecharacters indicate the same parts throughout all the views.

In the drawings,

Figure 1 shows a blank from which the cup is formed;

Fig. 2 shows an assembled cup and the manner of opening the same, theconstruction being slightly modified;

Fig. 3 shows another modification;

Fig. 4 shows in section still another form of the invention; and

Fig. 5 shows a side view of an assembled cu}; constructed in accordancewith Fig. 1.

eferring to the drawings and more particularly to Fig. 1, the numeral 1indicates a blank from which the cup is formed, having a water-proofcoating thereon. This blank is transversely creased along the dottedline 2 to provide the front and back walls 3 and 4 of the cup. The blankis further creased along its longitudinal edges to a point just belowthe transverse crease 2 to form the side walls 5 and 6, theselongitudinal creases being indicated by the dotted lines 7 and 8respectively.

At the opposite longitudinal edges of the blank and upon opposite sidesof the transverse crease are the angular extensions 8, 8*, 9 and 9", theedges of which diverge from this transverse crease.

The wall 4 is provided with the usual rounded edge 10 and the wall 3 iscut out or recessed at its outer transverse edge, this being indicatedby the numeral 11.

In the assembly of my cup, the walls 3 and 4 are arranged in parallelismand in clOSe proximity to each other. This operation brings the angularextensions 8 and 9 in superposed relation and also the angularextensions 9 and 9 in superposed relation. The side walls 5 and 6 arenow turned inwardly and secured to the longitudinal edges of the wall 3by means of any suitable adhesive. Having set forth the structure of thecup, I will now proceed to describe the arrangement for opening the samewithout subjecting the interior thereof to infection.

Secured to the longitudinal edges of the sides 5 and 6 adjacent to theirupper edges is a stiff longitudinal narrow strip 12. 13 and 14 indicatethe ends of this strip which are secured to the sides 5 and 6 by meansof any suitable adhesive.

In the modification shown in Fig. 2, the angular extensions are omittedand the side walls 5 and 6 are relatively wide atlthe bottom as at 17and 18 and gradually taper toward the top.

Fig. 3 shows a slightly modified form of the invention. In this figurethe strip 12 is bowed or arcuate longitudinally.

Fig. 4 shows another form of my invention. The strip 12 in this formlies flat against the wall 3 and is secured thereto her in which the cupis opened and has its ends extended around the longitudinal edges of theWalls 5 and 6 and secured to the wall 4 at 15 and 16.-

I will now proceed to describe the manfor use. Upon removing the cupfrom the receptacle for use, pressure is applied to the op osite sidewalls 5 and 6 by means of the ngers of the person using the same therebyopening the cup.

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the construction and method of using theinvention will be readily understood by those skilled in the art towhich the invention appert-ains and while I have described the operationtogether with the forms which I now consider to be the best embodimentthereof, I desire to have I it understood that other forms may b'e-emandrear walls, the frontwall being extended to form folded portions, saidfolded portions being secured to the rear Wall, thereby presenting acomplete cup; and an auxiliary strip secured to the folded portions andrear wall, said strip being made of paper and having an arcuateconfiguration and locatedbelow the top of said rear wall, said stripbeing adapted to separate the top of the front and rearwalls whenpressure is applied to the ends of the strip.
